` Application filed February 13, 1903- Serial No. 143,236. (No model.)

To a/ZZ whom, t may concern,.-

Beit known that I, EDWARD C. WYSONG, a citizen of the United States,residing at Eaton, in the county of Preble and State of Ohio,

have invented certain new and useful Im-y proveniente in Axle-Nut Wrenches, of which the following is a specification.

To secure axle-nuts against accidental displacement and to provide an operating means for loosening and tightening the same is the primal object of this invention.

In accordance with this invention the axlearm is provided with a spring-actuated lock arranged in an openingat the outer end, and the axle-nut is provided with a central opening for reception of the outer end of the lockbolt. Before the nutcan be turned in either direction the lock-bolt must be repressed. This is accomplished by providing the Wrench or Spanner with a releasing device, the parts cooperating, as will be readily understood from the subjoined description.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eecting the result reference is to be had tothe following description and draw-- ings hereto attached.

While the essential and characteristic features ofthe invention are susceptible of modiiication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective View showing the application of the invention to ,an axle-nut and wrench. Fig. 2 is a longitudinal section; Fig. 3 is a perspective view of the outer end of the axle-arm, showing more clearly the locking means for the axle-nut. Fig. 4 is a perspective view of the wrench.

Corresponding and like parts are referred to in the following description and indicated in all the views o f the drawings by the same reference characters.

The axle-arm 1 is provided at its threaded end with a longitudinal opening 2, in which is fitted a spring 3 and a lock-bolt 4, the latter being freely slidable Within the opening, but prevented from .turning therein. f The 5o lock-bolt is preferably angular in cross-section, and the outer end of the opening 2 is of corresponding shape to prevent rotation of the lock-bolt in any adj usted position.

The axle-nut 5 is provided in its outer end with an opening 6, adapted to receive the outer end of the lock-bolt4 and the inner end of the releasing device applied to the wrench. The outer end of the part 4 is adapted to enter the opening 6 and interlock therewith, so as to prevent rotation of the axle-n ut in either direction. opening 6 is of square or angular formation, and the outer end of the lock-bolt 4 is made of corresponding shape and is reduced, so as to form a shoulder 7 at the `base of the reduced portion to limit the outward movement of the lock-bolt, whereby it comes about flush with the outer end or side of the axle-nut. The reduced end 8 of the lock-bolt is outwardly tapered to facilitate its entrance into the opening G. y

The wrench 9 may be of any structural type commonly used in connection with axlenuts. To the successful use of the wrench in turning the axle-nut either on or 0E from the axle-arm the same is provided with a releasing device to engage with the outer end of the lock-bolt 4 and move the same inward, so as to disengage its outer end 8 from interlo'cking connection with the axle-nut. The releasing device consists, essentially, of a pin or rod 10, provided at its outer end with'a button 1l for the thumb or finger of the hand to obtain a purchase upon and provided near its inner end with an annular shoulder 12 to limit the movement of the part 10 with reference to the axle-nut. The pin or rod 10 is mounted in a guide 13, so as to turn and slide freely therein, said guide being a bracket or kindred support applied to or forming a part of the wrench. The releasing device 10 occu pies acentral position with reference to the nut-socket of the wrench, so as to enter the opening 6 of the nut and engage with the outer end of the lock-bolt in any position of the wrench upon the nut. In accordance with ,this invention it is not essential that the axlenut be screwed ti ghtu pon the axle-arm, since the lock device prevents loosening or movement thereof in either direction. Obviously the axle-nut may beinovedinward tocompensate for wear between it, the shoulder 'at In the preferable construction the i the inner end of the axlearm, and the ends ot' the hub, so to take up Wear and obviate the necessity for applying Washers to the axleaiins, as is commonly practiced. When it is required to turn the axle-nut, the wrench is iitted thereto in the accustomed Way, and the pin or rod 10 is pressed upon so as to disengage the part 4 from the axle-nut, after which the nut may be turned in the desired direction either for tighteningr or loosening. After the nut has been applied to the threaded end of the axle-arm and pressure removed from the pin or rod l0 the lock-bolt, under the influence of the spring 3, moves outward and projects the end Sinto the opening 6, thereby locking the nut against casual turning in either direction. In this connection it is to be understood that the nut must be turned to bringr the opening 6 in coincident relation with the part 8 before the latter will spring into said opening and interlock with and secure the axle-nut. p

The lock-bolt 4 may be of any crosssec tional outline and the opening- 2 of corresponding shape to prevent turning of the bolt. The lock, while preferably designed for axle-nuts, may be applied to any type of nut to prevent loosening thereof.

Having thusfully described the invention, what is claimed as new is- An axle-nut wrench of the character described, and provided with a nut-socket at one end, a bracket projected from the wrench adjacent the aforesaid socket and having a guide disposed thereon, said guide being located at approximately a central position with reference to the socket, a releasingr pin or rod rotatably and longitudinally slidable in the guide and provided upon its outer end with a button for manipulation thereof, and near its inner end With an annular shoulder to limit the movement of the same in applying the Wrench to the nut-lock, substantially as and for the purpose set forth.

ln testimony whereof l affix my signature in presence of two witnesses.

EDWARD C. WYSONG.
